**5A.1 INTRODUCTION This appendix provides supplementary results from the engineering analysis, including**  **information about the distributions by price for each of the representative units analyzed. The supplementary results include the following:**  **1. No-load (core) losses versus manufacturer's selling price 2. Load-losses (coil) versus manufacturer's selling price**  **3. Transformer weight versus efficiency This appendix reproduces Table 5.2.2 from Chapter 5 as Table 5A.1 below for reference,**  **and provides a summary of the engineering design lines and the specifications of each of the representative units.**  Table 5A.1 Engineering Design Lines (DLs) and Representative Units for Analysis **PC* DL** Type of Distribution
